Bond 1)___________________ is an uneven distribution of electronic charge along a covalent bond, which results from electrons being unevenly shared as a result of differences in attraction to each atom of the bond.  This difference in attraction is the result of differences in 2)______________________, an idea proposed by Linus Pauling, which says that even formally charge-neutral atoms may attract electrons more strongly than others as a result of differences in atomic size and the the atom's valence shell energy level.  In this way, such bonds may be 'in-between' the more idealized fully ionic and covalent sorts of bonds.  The polarization of such bonds can be expressed with either 3)________________ notation, which is a way of expressing a partial positive or negative charge on the bonded atoms, or 4)_________________ notation, which 'points' from the more-positive to the more-negative of the atoms in the bond.  The presence of such bonds may or may not render a molecule overall to show a similar charge-imbalance, known as a 5)__________________, depending on the geometry of the molecule and the way that individual bond polarizations add together.

Roughly speaking, chemical bonds can be classified as either 1)___________________, which are bonds between oppositely charged ions held together by Coulombic attraction, or 2)____________________, which are bonds that result from sharing of electrons between atoms which would otherwise be valence-electron deficient.  Electron sharing to form bonds is principally observed to occur between 3)______________________, and allows the bonded atoms to satisfy the 4)_______________________ rule.   5)___________________ structures are symbolic representations of compounds formed with this sort of bonding, where bonds are represented with lines between bonded atoms, and 6)_____________________ are represented by two dots.  Some such structures may contain 7)_______________________ bonds, which are particularly strong bonds between adjacent atoms, result in unusually short distances between them, and are not seen in ionic bonding.  If there are any heavier elements present, particularly those from the third row of the periodic table and lower, 8)_______________________ may be observed, in which d-orbitals become involved in bonding and the valence shell may show more than the normal number of electrons being involved.
